  Since the heat exchange system 100 arranges the heat exchange tank 30 and the heat storage tank 10 adjacent to each other, the occupied space can be reduced. In addition, by placing the hot water receiving tank 20, the heat exchange tank 30 and the heat storage tank 10 in the basement and buried in the earth and sand S, in particular, the occupied space on the ground can be greatly reduced, Since heat dissipation can be suppressed, thermal efficiency is also improved. Furthermore, the fact that the hot water receiving tank 20, the heat exchange tank 30, and the heat storage tank 10 are adjacent to each other is also effective in improving the thermal efficiency.

  In the heat exchange system 100, since the hot water receiving tank 20, the heat exchange tank 30, the heat storage tank 10 and the like arranged in the basement are in contact with the surrounding earth and sand S, after the heat exchange system 100 is constructed, When time elapses, the temperature of the surrounding earth and sand S rises due to the heat generated from the hot water receiving tank 20, the heat exchange tank 30 and the heat storage tank 10 that are in operation and at a high temperature, and the hot water receiving tank 20, heat exchange It becomes a high temperature equivalent to the tank 30 and the heat storage tank 10, and the state is maintained. For this reason, the effect of suppressing heat dissipation is further enhanced, and the thermal efficiency is greatly improved.

  Moreover, since the surrounding earth and sand S, such as the hot-water receiving tank 20, the heat exchange tank 30, and the heat storage tank 10, contains the substance (far-infrared radiation substance Q) which has a far-infrared radiation function, it was heated by the heat medium. Due to heat radiation from the hot water receiving tank 20, the heat exchange tank 30, or the heat storage tank 10, the water present in the earth and sand S is efficiently heated by the far infrared rays emitted from the far infrared substance Q heated together with the earth and sand S. As a result, since the surrounding earth and sand S such as the hot water receiving tank 20, the heat exchange tank 30, and the heat storage tank 10 are kept at a high temperature over a wide range, the heat retaining effect is remarkably enhanced, which is extremely effective for improving the thermal efficiency.

  In addition, the far-infrared radiation material in the earth and sand S in the heat storage state, the earth and sand S is heated by heat radiation from the hot water receiving tank 20, the heat storage tank 10 or the heat exchange tank 30 heated by the heat exchange medium (hot water) Since far infrared rays are radiated from Q, the effect of warming the liquid (hot water) inside the hot water receiving tank 20, the heat storage tank 10, and the heat exchange tank 30 is obtained.

  Here, the far-infrared radiation material Q in the earth and sand S can be mixed in the earth and sand S to be backfilled when the hot water receiving tank 20, the heat exchange tank 30 and the heat storage tank 10 are buried underground. Moreover, if the heat exchange system 100 is constructed in the underground portion of the land that contains a lot of far-infrared radiation material Q in the earth and sand S in a natural state, the same effect by far-infrared as described above can be obtained. The far-infrared emitting substance Q is a substance having a function of emitting an electromagnetic wave having a wavelength of 4 μm to 1000 μm.

The far-infrared emitting material Q is not particularly limited, and natural ceramics or artificial ceramics can be used. For example, Al ₂ O ₃ , SiO ₂ , MgO, ZrO ₂ , 3Al ₂ O ₃ .2SiO ₂ (mullite ), ZrO ₂ · SiO ₂ (zircon), 2MgO · 2Al ₂ O ₃ · 5SiO ₂ (cordierite) and the like are suitable. Here, the ceramic is a general term for inorganic compounds of various metal elements such as aluminum, silicon, magnesium, zirconium, and titanium, oxygen, nitrogen, carbon, boron, and the like, and composite compounds thereof.

  As described above, since the heat exchanger 50 can be taken in and out with respect to the heat exchange tank 30 relatively easily, when a scale adheres between the plurality of tubes 56 due to long-term use or the like, As shown in FIG. 4, it is lifted from the heat exchange tank 30 (see FIG. 2) by being lifted by a crane hook F through a dedicated jig X, and immersed in a cleaning liquid R in a cleaning tank 80 provided in the vicinity thereof. And can be washed. After completion of the cleaning, as shown in FIG. 5, the heat exchanger 50 can be pulled up from the cleaning tank 80 and returned to the heat exchange tank 30 (see FIG. 2).

  In the heat exchange system 100, the hot water receiving tank 20, the heat exchange tank 30, the heat storage tank 10, and the like are disposed in the basement so that the hot water receiving tank 20, the heat exchange tank 30, the heat storage tank 10, etc. are buried in the earth and sand S. However, the present invention is not limited to this. For example, a hot water receiving tank 20, a heat exchange tank 30, a heat storage tank 10 and the like placed on the ground are covered with earth and sand to form a bank, or a tunnel shape The hot water receiving tank 20, the heat exchange tank 30, the heat storage tank 10 and the like are accommodated in the horizontal holes, and then backfilled with earth and sand, so that the hot water receiving tank 20, the heat exchange tank 30, the heat storage tank 10 and the like are earthed.

For this reason, the effect which suppresses heat dissipation is very high, and thermal efficiency can be improved significantly.

  Moreover, since the surrounding earth and sand S, such as the hot water receiving tanks 521, 522, 523, and 524, the heat exchange tanks 531, 532, 533, and 534, and the heat storage tanks 511 and 512, contain the far-infrared radiation material Q, the earth and sand S At the same time, the water present in the earth and sand S is efficiently heated by the far-infrared radiation emitted from the far-infrared emitting material Q whose temperature has risen. As a result, the hot water receiving tanks 521, 522, 523, 524, the heat exchange tanks 531, 532, Since the surrounding earth and sand S such as 533 and 534 and the heat storage tanks 511 and 512 are kept at a high temperature over a wide range, the heat retention effect is remarkably enhanced, which is extremely effective for improving the thermal efficiency.

  As described above, the far-infrared emitting material Q can be mixed in the earth and sand S when the earth and sand S is backfilled, but the heat exchanging system is installed in the underground portion of the land containing the far-infrared emitting material Q in the earth and sand S. The same effect can be obtained by constructing 500.
